45W HP laptop charger

This 45W AC adapter replaces original HP chargers with a 4.5x3.0mm blue tip connector. It suits owners of compatible Stream, Pavilion, Envy x360 and Notebook models who need a new power supply. The unit accepts 100-240V input at 50-60Hz for worldwide use. It is a direct replacement for the listed part numbers.

Blue tip connector fit

The 4.5x3.0mm blue tip matches the exact port on the supported HP laptops. It will not fit devices that require the larger 7.4x5.0mm connector. This physical difference prevents accidental use on incompatible hardware. Users must verify their laptop's port size before connecting.

Compact travel-ready build

The adapter body is designed for portable daily use with a standard cable length. The 100-240V input handles mains voltage in different countries without a separate transformer. No extra accessories or software are bundled in the package. The unit delivers 19.5V at 2.31A for the rated 45W output.

Questions about this item

Will the 4.5 x 3.0 mm blue-tip connector wear out and need replacing?

The connector is a fixed part of the cable; if the tip or cable frays the whole adapter must be replaced.

What limits continuous 45 W output during all-day use?

The adapter is rated for 19.5 V at 2.31 A up to 45 W; sustained loads at that level will hit the thermal limit of the sealed unit first.

How much heat and fan noise does the brick produce when running 24/7?

There is no fan; the unit relies on passive convection, so it runs silent but the case becomes warm under continuous 45 W load.
